Asteroid alert: NASA tracks a rock taller than Big Ben but will the asteroid hit tomorrow?


Asteroid XW is an Apollo-type rock, meaning it crosses Earth’s orbit on a trajectory similar to Asteroid 1862 Apollo.

NASA estimates the rock measures somewhere in the range of 144ft to 324ft (44m to 99m) in diameter.

At the upper end of NASA’s estimate, the asteroid is taller than Big Ben’s clocktower at Westminster Palace in London.

The asteroid is also taller than the Statue of Liberty in New York, US, and is as long as a football field.

At the lower end of NASA’s size estimate, the asteroid is comparable in height to the Arc de Triomphe in Paris, France.
